Appleman ined April 1s, 1894.. seria No. 507,422. (No medew To all whomit may concern:

Be it known that I, JAMES V. BRADY, a citizen of the United States,residing at Sonora, in the county of Hancock and State of Illinois, haveinvented certain new and useful Improvements in Cultivators; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.Vv

This invention relates to cultivators.

The object is to produce a cultivator, in which the teeth or shovels maybe adjusted independently of the drag-bars, in groups or pairs, toregulate the depth to which the teeth enter the ground; andl further, inwhich each tooth may be separately adjusted to adapt the cultivator tothe width of therows of the crop. Y

With this and other objects in View, theinvention consists in thecombination of parts hereinafter described and claimed.

The invention is illustrated in the aecomclamps, and the toothed Shanksseparately and adjustably held by the clamps. Fig. 2-

is a view in side elevation, showing a crossbeam adjustably held on thedrag-bar and the toothed shanks clamped to the beam, also, the relativelengths and arrangementof the Shanks. Fig. 3- is a view in frontelevation of one of the slotted cross-beams, showing the stirrup-clampsadj ustablyseated in the slots, and a set-screw or bolt passing throughan enlargement of the beam to a vertical, central opening and bindingagainst the drag-bar therein. same, showing the slots in the beams andthe threaded extremities of the U-shaped clamps projecting through theslots and provided with lock-n uts. Fig. 5 is a fragmentary view showinga modied form, in which the central enlargement of the beam is chamberedto receive the curved end of the drag-bar which is slotted laterally andheld by binding screws or bolts passing laterally through theenlargement and the slots, above and below l the other partv of thebeam, the construction Fig. 4- is a top plan view of thevand arrangementpermitting Aslight play of the beam. v y v In the drawings, A,represents the dragbars of a cultivator, the rear ends, a, a, of whichare flattened and curved downward.

B, represents slotted cross-beams which are respectively provided aboutmidway of their length with an enlargement, b, projecting verticallyfrom opposite sides of the beam, at a right angle thereto. Thisenlargement is vertically and centrally bored at b2, to receive thecurved extremity of the drag-bar to which the beam is adjustablyconnected by a binding screw, bolt, or other device, h3.

C represents stirrups, yokes, or U-shaped clamps, which are adj ustablyseated in perforations or the slots, b4, toward the outer ends 'of thebeams, with their curved portion projecting through the slots and belowthe lower face of the beams, and their extremities threaded to receivelock-nuts, c, c.

D, represents curved toothed Shanks, here shown arranged in pairsortwooneach beam. These shanks areisepa'rately securedfto the under sideof the beam, bybeing passed.

through the depending stirrups, andare adjustablyl heldl by thelock-nuts, c, c, either rigidly or yieldingly, as desired. One shank ofa pair is given'an increased length by which the shanks may berelatively adj usted to work in a follow-up series, as shown in Fig. lof the drawings, or parallel, in pairs, or fours, ac-

cording to the number employed.

Where the soil is hard or stony, it may be found necessary to give thecross-beams slight play, and avoid shocks or strains on the teeth. Toeffect this, the construction illustrated in Fig. 5 is employed, andconsists in chambering the central enlargement of lthe beams or makingrit U-shaped, to receive the flattened extremities of the drag-bars,which are of a width sufficient readily to admit of slots beingformeditherein, without materially weakening them, and through theseslots, screws, bolts, or pins from the enlargement are passed and workloosely therein.

Among the numerous and important ad vantages of this invention maybementioned, the ease and convenience with which an entire rearrangementof the teeth, shovels, or points, may be effected, to adapt thecultivator IOO to perform work of various kinds efficiently; also theconnection between the cross-beams and the Shanks, by Which the lattermay be Separately and accurately adj usted and rigidly or yieldinglysecured.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The eolnbin ation with a drag-bar, having its rear end curveddownward, of across-beam provided about midway of its length with anenlargement having a central vertical perforation or chamber and bindingscrews or bolts to retain the drag-bar in desired position, andprovided, further, with slots toward its ends, and of stirrups or yokesset in the slots with their curved portion downward and having theirextremities threaded and provided with nuts, all substantially as andfor the purpose described.

2. The combination with drag-bars, having all substantially as and forthe purpose set t forth.

In testimony whereof I aftix my signature in presence of two witnesses.
